It's funny to me that no one has ever claimed to have accomplished anything globally significant while using nootropics to my knowledge. Mood elevators or stimulants, sure. Hitler was all into those. But, nootropics? I mean, I guess it depends on where you draw the line of what is considered one.
Coffee. (Although I'm not totally sure that's considered a nootropic in this context.)
Adderall.
Again, probably not nootropics, but they serve the same function: wake your brain up enough to accomplish something you may not have had the cognitive ability to do without it.
